A derogatory term used to refer to a young girl (late teens/early 20s) who is intelligent and well-educated, but naive and gullible. She thinks she knows it all when, in fact, she has almost no understanding of the world other than what she was told in the classroom. She thinks knowledge compensates for good judgment and experience.
